# How do you convert 314159 into scientific form?

$3.14159 \times {10}^{5}$
It has to be a number greater than 1 and less than 10 times a power of ten. In this example we had to move the decimal point 5 places to the left so to have a number between 1 and 10. In other words we had to multiply the number by ${10}^{-} 5$. So now in order to counteract this operation we multiply by ${10}^{5}$.
$314159 = 314159 \times {10}^{-} 5 \times {10}^{5} = 3.14159 \times {10}^{5}$
